1321-3R100-C

The 1321-3R100-C is an external protection device that is typically used with Allen-Bradley drive products. With a line reactor installed at the input line connections of the adjustable frequency AC drive, line disturbances such as sudden voltage increase and decrease, Current spikes and harmonics are absorb by this device thus, preventing it from entering the VFD and damaging the frequency drive.

A line filter is basically an inductive load made of coils of wire to form a magnetic field. The magnetic field reacts to the flowing current through the input line thus the name Line Reactor.

The 1321-3R100-C is recommended by Allen-Bradley for use with their very drives such as PowerFlex 700, PowerFlex 700S, PowerFlex 400N, PowerFlex 750, PowerFlex 400, PowerFlex Low Voltage drives and PowerFlex DC Drives. This does not mean that the line reactor may be used with the entire product family, the line reactor is compatible with one or a variety of products within these PowerFlex families. Ensure proper sizing of line reactor by referencing to the Fundamental Amperes of 100A, Frequency of 50 / 60 Hertz for both Line and Load, Inductance Tolerance of +/-10% and Rated Voltage of 600V AC with terminal blocks or 690V AC with box lugs or tab terminals.

Line reactors are installed within the enclosure where the VFD is mounted. It may be installed at the drive’s input and output line connection, with multiple drives or with multiple motors. A 3-Phase reactor may also be used with 1-Phase applications. This is achieved by utilizing the outside coils of the unit, leaving the middle coil without a connection. The Allen-Bradley 1321-3R100-C is a line reactor under the 1321 series of power conditioning products from Allen-Bradley. This product is designed to keep equipment operating longer by absorbing power line disturbances that can adversely affect drive operation. The 1321-3R100-C reactor is a 3-phase line reactor with a fundamental current rating of 100 Amps. The inductance of the reactor is 0.45 Millihenry. The power dissipation of the reactor is 108 Watts. The dimensions of the 1321-3R100-C line reactor are 8.4 x 10.8 x 7.8 inches (H x W x D). The approximate weight of the inductor is 67 pounds. Reactors such as the 1321-3R100-C line reactor which have 55 to 160 Amps ratings are supplied with box lugs for termination. The maximum and minimum recommended wire size for termination is 120 millimeters square and 27 millimeters square, respectively. The 1321-3R100-C line reactor comes in an open IP 00 rated enclosure. It is compensated for the additional current caused by harmonics. The maximum rated voltage is 690 Volts AC. The maximum switching frequency is 20 kilohertz. The fundamental frequency is 50/60 Hertz for line/load. The average temperature rise is 135 degrees Celsius. The dielectric strength is 3000 Volts RMS.
